Application file 0ctober 9, 1917. Serial No. 195,617.

T0 aZZ whom 2% may concern Be it known that I, MICHAEL J. lKELLY, citizen of the United States, residing at Ocean View, in the county of San F rancisco, State of California, have invented a new and nseful Pipe-Coupling, of which the following is a specification in such full and clear terms as Wlll enable chose skilled in the art to construct and use the same.

T his invention relates to a pipe sleeve for use on railway cars to prevent the pipe systems from being dislodged or broken when the cars are coupled and uncoupled.

It Will be understood by those skilled in the art that both freight cars and passenger cars are heavily jarred during the coupling and uncoupling and during the operation of the trains. The result of this is that the brake pipes and train signal pipes Which are commonly suspended beneath the cars are requently broken loose from their securing menus, and either drop down on the track, or become inoperative because of breakages.

It Wll be understood that, while the pipe coupling has been especially referred to in connection with train pipes and such uses, it may be equally well used in conj unction W1th any pipe system which requires such a support as is herein contemplated.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the drawings in Which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Figure 1 is a perspective VieW of the pipe sleeve showing the means for securing it to the car,

Fig. 2 is a longitudinal section of the sleeve, and

Fig. 3 is a transverse vertical section of the sleeve shoW1ng the secur1ng means in sect1on as Well.

The numeral 1 indicates the sleeve which has threads for the reception of the pipe as indicated at 2 and 3. One side of the sleeve is fiat as indicated at 4, and it is provided with a broad groove, as indicated at 5 as well as a groove across the fiat side, as intion of the groove in the sleeve and snitable screws or bolts 9 and 10 are used to secure the plates and the sleeve in place against the inside of the car trame.

It Will be observed that, before the sleeve can be unshipped from its securing means,

the plate 7 must be forced ofi its bolts, and owing to the fiat base of the sleeve it is possible to assemble the pipes therein when the sleeve has been fastened in place under the car frame, since the fiat portion of the sleeve 5 prevents it from being rotated when the clamp 8 has been secured in place.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent of the United States is as fol lows, express reservation being made of per missible modifications:

A threaded pipe sleeve having a circum ferential groove around its central portion and a fiat base, a fiat plate upon which the sleeve rests and Which fits said groove, and a clamp fitted into the groove around the sleeve, the fiat plate and clamp adapted to se cure the sleeve to an object.

In testimony whereot 1 have hereunto set go my hand this 2" day of October, A. D. 191?,

MICHAEL J. KELLY.
